Fetal nutrition.
The extensive literature on nutrition in pregnancy is reviewed with special reference to international experience, including observations on nutritional trials in pregnancy, pregnancy during famines caused by war, and studies of birth-weight in relation to pregnancy interval, parity and multiple pregnancies. Recent research on the significance of fetal nutrition suggests that "small-for-dates" infants, i.e., those that are developmentally retarded in utero, suffer long-term developmental sequelae. A high world-wide incidence of small-for-dates births was reported by the World Health Organization in 1960.Although a definite correlation has been found between socio-economic status and birth-weight, it is not known to what extent the smaller birth-weights observed in the lower socio-economic groups can be improved by specific nutritional measures. In addition to the general advice given on maternal nutrition and family-planning, further studies are needed to determine the precise means of achieving improvement in fetal nutrition and a better outcome of pregnancy.
